You don't need to overclock or flash your card to increase the refresh rate, just do it under display properties.

As far as flashing I don't see anything you could flash to upgrade an X300SE. The X300 has a 50MHz core clock increase and moves to 128-bit memory, so the best you could do would be download ATITool and move the core up by 50MHz. The 64 to 128 bit memory interface is not something you can change.
